You would use something like the `Future` type mentioned in the proposal:

	func process() {
		let bigDataFuture = Future { await loadWebResource("bigData.txt") }
		print("BigData scheduled to load")
		
		let smallDataFuture = Future { await loadWebResource("smallData.txt") }
		print("SmallData scheduled to load")
		
		let bigDataResource = await bigDataFuture.get()
		let smallDataResource = await smallDataFuture.get()
		// or whatever; you could probably chain off the futures to handle whichever happens first first.
		...
	}
